Bought cheap ones off the Internet for mine in the past but never really happy with them so went for the real thing in the end, look so much better and better quality in most cases, think I got them from cox motors in the end, they were about £50 but personally think its worth the money
They fit nicely, are decent quality and dirt cheap. I had some official Civic ones but they didn't fit right as they were for the 2009 onwards model. In terms of quality there is no difference - the ones off ebay are actually thicker. However, the ones from Honda look a little better as they have the logo on them.
